Does anyone have information on a Brodie kit sail? I found one of these on craigslist. This is a sail rig kit that was sold in the early/mid 1960's. One thing that seems to be unusual is that the mast is not stepped on the bottom of the canoe, but it appears to be stepped on a casting in the center of the mast thwart. This might make the mast a bit less secure than the traditional design. Any experience or knowledge of this product? Thank you.
